Overview

Endoscopic ultrasound and Somatostatin receptor scintigraphy (SRS) (octreotide scan) may be helpful in the diagnosis of Zollinger-Ellison syndrome caused by gastrinoma.

Other Imaging Findings

Other imaging studies that may be helpful in the diagnosis of Zollinger-Ellison syndrome include:

• Endoscopic ultrasound
• Somatostatin receptor scintigraphy (SRS) (octreotide scan)

• Note: A-D. 37-year-old male with MEN 1. The patient was injected with 6.4 mCi In-111 octreotide, and images were acquired in the anterior and posterior projections at 4 hours (3A) and 24 hours (3B). SPECT images were also obtained at 24 hours (3C, axial, and 3D, coronal). Findings are consistent with metastatic somatostatin-receptor-positive malignancy involving the lymph nodes either in the peripancreatic or porta hepatis region.
